    Hello all,

    I am working on an old Benrus day - date watch also known as an ETA 1015. I have repaired the watch and sorted it out. I have looked at the setting arrangement but it doesn't work the way I think it should. This is a nice little watch. I hope someone can lead me into to light.

    Thanks,
    Guy

    Try this. Set the watch ahead until it shows the correct DAY. STOP! Back up to 8:00 pm and the day should back up one day. Set AHEAD until day and date BOTH change. STOP! Back up until the day backs up one day (about 8:00 pm), then set ahead until BOTH day and date change. Every time you do this sequence, you should be able to keep the watch on the correct day, advancing the DATE with each repitition. Once the correct DAY and DATE show, set the watch to the correct time, AM or PM.

    Doug,
    Success indeed! The seesawing back and forth between 12AM (00Hr) and about 7:30 PM (1930 Hr) advances the day; the date just jumps the returns to where it was. To advance the date one must crank through the hours to get to the correct date. However if the watch is on the bench just lift the crystal, pull out the stem then nudge the hand to the correct date.

    Guy,

    I know I'm a bit late to this, but if this is one of the "porthole" day-date models, the date pointer should jump forward when the crown is pressed in. At least that's what mine does.

    Indeed, to increment the date forward one day at a time press in on the crown (like a stop watch). hope that helps.
